    摘要： The invention provides a combustion apparatus which can inhibit an NOx generation even in the case of promoting a mixing between a high-temperature combustion gas and an air so as to intend to reduce an unburned combustible. In a combustion apparatus provided with a burner burning a fuel within a furnace in a theoretical air ratio or less, and an air port supplying a combustion air for a shortfall in the burner, a supply apparatus for supplying a nitrogen oxide generation inhibiting gas is provided in a mixing region between the both or near the mixing region. Further, the invention provides a wind box which can inhibit an NOx generation even in the case of promoting a mixing between a high-temperature combustion gas and an air so as to intend to reduce an unburned combustible. In a wind box having an air port arranged in a back flow side of the burner and supplying a combustion air for a shortfall in the burner, a supply apparatus for supplying a nitrogen oxide generation inhibiting gas is provided in a mixing region between the both or near the mixing region.

    摘要： There is disclosed a solid fuel boiler including: a furnace including a plurality of solid fuel burners and a furnace wall to perform horizontal firing; a duct through which a part of combustion exhaust gas recirculates to a furnace from a downstream side of the furnace; heat exchanger tubes disposed on a furnace wall and in a heat recovery area of the furnace; and recirculation gas ports via which the recirculation gas is supplied to a reducing flame portion of the burners in the furnace without combining the gas with a flame in the vicinity of an outlet of the burner, so that molten ash is prevented from firmly sticking to the furnace wall and thermal NOx, fuel NOx, and unburned carbon.
